Answer #1

Answer NADH and FADH2

Explanation

ETS is the final stage of respiration that occur in inner mitochondrial membrane. There are several proteins in mitochondrail membrane that transfer electone and create a proton gradient, which inturn lead to ATP production. ATP is used by the cell for metabolic activities.

NADH and FADH2 that are produced from glycolysis, pyruvate oxidation, and the citric acid cycle donate electrones to complex I and complex II respectively.Thus they get oxidised.

Mitochondria produce most of the cell's ATP by oxidative phosphorylation. Electrons from NADH and FADH2 formed in the TCA cycle are transported through the electron transport chain (ETC) which consists of four complexes (I, II, III and IV). Hereby, a proton gradient is formed across the inner membrane of the mitochondria which is used by the ATP synthase to form ATP. In isolated mitochondria, oxygen consumption rate (OCR) and rate of ATP synthesis can be determined, respectively. Seahorse and NOVOstar...
